footnotes in the book of life

Have you ever observed how music serves as footnotes in your life? You're idling your time in front of the television, switching channels; you unexpectedly hear a long lost tune and it immediately throws you back in time ...to a place, different; ...to a time, nostalgic. As the music catches on and the lyrics seem to appear onto your lips from nowhere, your mind is flooded with events and thoughts that belong to a different time, that probably defined a different you then, and you think; ...you think about your life, begin to recollect how you were then and what you are now. Mostly you'll observe the good changes and that will make you happy and proud of yourself. But at times, you'll stumble upon the mistakes you made then, and you'll now resolve to take corrective measures.
It all happens in there. You chance upon a peppy number from the past and all the good times flood in; the song that epitomized the party atmosphere during college days, the one that was the mainstay during dance competitions when you forgot everything else and jumped around, even though you couldn't dance to save your life.
A soulful melody reminds you of your private moments; the times when,cuddled under the blanket in winter, with the same song serenading the silence of the night, you introspected and thought about your future, or about your family, friends.
Music livens up your past.It opens different chapters from your past, depending on the song or tune; some good some not so good, but nevertheless, very nostalgic.
